Mortgage Affordability Calculator
Estimated Affordability
Tip: Lenders often use a 28% rule for housing costs and a 36% rule for total debt. This tool helps you see where you stand.
How to Use This Tool

Formula and Logic
This calculator uses standard lending guidelines: it applies the 28% rule for housing costs and the 36% rule for total debt-to-income ratio. The monthly mortgage payment is calculated using the standard amortization formula, factoring in principal, interest, property taxes, and insurance (PITI). The maximum home price is derived by working backward from the affordable monthly payment.
Practical Notes
- Interest rates significantly impact affordability; even a 0.5% change can alter your budget by thousands.
- Property taxes vary by location—research local rates for accuracy.
- Home insurance costs depend on property value and location; get quotes for precision.
- Maintain a debt-to-income ratio below 36% for better loan approval chances.
- Consider additional costs like closing fees and maintenance in your overall budget.
